Congress Hears Testimony From Chemical Company Executives On PFAS Contamination

Executives from three major chemical companies — DuPont de Nemours, Inc., The Chemours Company and The 3M Company — testified for the first time to Congress about widespread contamination from the group of nonstick, fluorinated chemicals broadly called PFAS.

The so-called “forever chemicals” persist in the environment, are linked to ill health effects, and have been found in numerous water systems in the Ohio Valley.

The hearing — the third on PFAS contamination by the House Committee on Oversight and Reform’s Subcommittee on Environment — explored the extent to which companies that make PFAS chemicals knew about its impacts on human health and the environment and how they should be held accountable.

“These companies with us here today have screwed up and we need to hold them accountable for doing so,” said Committee Chairman Rep. Harley Rouda from California. “I hope the people representing those companies here today will admit their mistakes so that we can all move forward and achieve what I believe is our common goal: to clean up contaminated sites, stop exposing innocent people to toxic chemicals and making sure that all Americans have clean water and clean air.”

Concern over PFAS contamination has grown nationwide. The Environmental Working Group estimates the drinking water systems of more than 700 communities are contaminated with PFAS. Perfluoroalkyl chemicals were used to make nonstick products and are found in some flame retardants including firefighting foam.

“We support legislation to list PFOA and PFOS, and only those two, as hazardous substances under CERCLA. That’s further than the other companies here are willing to go today, but that’s what we believe is correct,” he said. “What we know about those chemicals is that they’re bio-persistent. That’s enough to know that there’s a clear concern for those chemicals within society at this point in time, and we feel for that reason they should be regulated.”

DuPont no longer makes PFAS chemicals. It split off its fluorinated chemicals business in 2015 to Chemours. A representative from Chemours said that company did not support such regulation. Chemours and DuPont are engaged in litigation over the split. Chemours argues DuPont misrepresented the environmental liabilities associated with PFAS chemicals.

3M’s Senior Vice President of Corporate Affairs, Denise Rutherford, doubled down on her company’s claim that there are no negative health effects from PFAS exposure.

“When we look at that evidence there is no cause and effect for adverse human health effects at the levels we are exposed to as a general population,” she said.

That didn’t sit well with some Democrats, including New York Rep. Alexandria Ocasio-Cortez who said this position goes against findings from government agencies and 3M’s own scientists.

The federal government’s Agency for Toxic Substances and Disease Registry says some studies in humans with PFAS exposure have shown: effects on growth, learning, and behavior of infants; an increase cholesterol levels; effects on the immune system; and an increase in the risk of cancer.

The hearing began with testimony from two attorneys whose lawsuits against DuPont and 3M unearthed thousands of internal company documents that showed both companies knew the chemicals were dangerous to human health and the environment for decades, but didn’t tell its employees or federal regulators.

Amid controversial proposals to change the law protecting rare species, the Running Buffalo Clover is an example of a successful recovery. It joins about 2.5 percent of threatened and endangered species (42 species) that have been taken off the list, or delisted, due to recovery. There are still 1,663 U.S. plants and animals on the endangered species list.
